How to drive a relay using Microcontrollers

This post will outline how you can drive a relay using micro-controllers like AVR. Concepts are same for any other micro-controller used either in standalone mode or embedded in a development board like Netduino or Arduino. Before we begin, I want to introduce the relay to you. If you already know, then you can skip … Continue reading

Controlling DC Motors using AVR Microcontrollers

This tutorial provides step-by-step instructions on how to use an AVR microcontroller (in this example an ATTiny2313) to control two DC motors using L293 motor driver. While the microcontroller can act like a brain through software and control signals from its input/output pins, it lacks muscles. Muscles to the “brains” are provided by motors, actuators … Continue reading
